SPECIFICATION forming part of Letters Patent No. 693,977, dated February 25, 1902.

Application filed May 17, 1901. Serial No. 60,748. (No model.)

To all whom it may concern:

Be it known thatI, WILLI M LOWERY M R- SHALL, of the town of Port Perry, in the county of Ontario, Province of Ontario, Canada, have invented certain new and useful Improvements in Vehicle-Gears, of which the following is a specification.

My invention relates to improvements in vehicle-gears; and the objects of the invention are, first, to improve the construction of the axle-arm, so as to minimize the friction of the hub of the'wheelwhen turning on the arm and at the same time so construct the arm that it will be easy to replace when worn or broken secondly, to improve the construction of the hub, so that the boxing may be readilyplaced in position in the center thereof or removed when worn preparatory to the insertion of a new boxing; thirdly, to devise a slight, strong, and cheap bolster .in which it will not be necessary to brace the end uprights; fourthly, to improvethe construction of the rear hounds of the runninggear, and, fifthly, to improve the construction of the reach and the connection of the tongue to the reach and axle, so as to throw the draft directly onto the reach and axle in stead of, as heretofore, above the level of the axle. To carry out these objects I have constructed the arm of the axle, the boxing of the hub, the hounds, bolsters, reach, and con nections of the tongue to the axle and reach in the manner which I shall now particularly describe, reference being had to the accompanying drawings, forming part thereof.

Figure 1 is a perspective view of a wagongear, showing the parts involved in my invention. Fig. 2 is a perspective detail showing the sand-board and fifth-wheel support for same, through which the axle extends, and the connection of the front end of the reach to these parts. Fig. 3 is a detail of the clevis to which the tongue is connected. Fig. 4 is a detail of the sand-board. Fig. 5 is a detail of the fifth-wheel. Fig. dis a detail of the hub, showing the hub and axle-box partially in section. Fig. 7 is a detail of the end nut. Fig. 8 is a detail of the hub. Fig. 9 is a detail of the boxing. Fig. 10 is a detail of the staple which secures it in position on the hub. Fig. 11 is a detail of the axle-arm. Fig. 12 is and arms thereof.

adetail showing the construction of the end of the bolster and uprights.

A A are the axles of the wagon or vehicle,

which are made in two longitudinal sections or bars a Ct, semicircular in cross-section. The bars Ct a extend from end to end of the axle The two bars a ct 0f the front axle A extend through the divided sleeve B, forming portion of the fifth-wheel B, the central rib b of the divided sleeve holding the two bars apart in thecenter.

0 represents blocks located one on each side .of the central sleeve B and securely held in position byv the bolt 0, extending therethrough.

The blocks 0 are provided with top and bottom side flanges 0, so as to hold them from displacement. with forwardly-extending lugs 12, which extend holes p D is a clevis whichisprovided with the rear vertical hole (1 and the front holes cl, horizontally dis posed. The king-bolt 01? passes through the holes I) in the lugs b and the rear hole cl of the clevis D.

E. is a tongue, which is connected to the clevis by the cross-bolt e, extending through the holes d.

through The fifth-wheel B is provided F represents the arms on the ends of the axles, both the rear and front axle being provided with arms formed in identically the same manner. The arms F comprise the inner sleeve portion F, provided with the inner flange f and the central barf, extending through the sleeve portion outwardly. The bar f is provided with the side flanges f? both at the top and the bottom, which extend over the bars a a. The ends of the bars f and the bars Ct a are both reduced, so as to 1 present a threaded circular end f for the end nutf. The arm F is tapered from end to end, the smallest diameter being necessa rily at the outer end and isheld' in position by the rivet f All the arms are constructed in this manner. The boxing G has an internal taper to correspond to the taper of the arm. It will now be seen that between the boxing G and the bars Ct at of the axle'there will be oil-spaces formed on each side of the barf, and thus the arm will be kept perfectly lubricated, and as the boxing is rotating only on the tapered outer edges of the ICO bar the friction on the arm and boxing will be reduced to a minimum.

The boxing G is held in position in the hub by means of the side ribs G, fitting into corresponding longitudinal recesses 72, in the hub II, and the staple-bolts G having the areshaped end fitting into recesses in the end of the hub and extending through recesses h in proximity to the recesses h, the opposite end being provided with nuts 72 The means above described securely holds the boxing in place in the hub, preventing both longitudinal and circumferential displacement of the boxing. When the cap-nut 7" is placed in position, the wheel is securely held in place on the arm.

From the above construction it will be readily seen that the boxing-hub may be readily inserted in place or replaced when worn.

On the inner end of the front arms f are formed lugs f, which are connected by the braces I, hooked into holes in the lugs to the curved metal-bound cross-bar E on-the tongue. The ends of the braces I extend through the metal-bound cross-bar and are provided at the front end with suitable huts t', whereby the tongue may be adjusted to an exact center. The whiffietree (not shown) is secured on the bolt J, which extends through the spring-plate J, held on the tongue, and through the cross-bar E.

B is a sand-board which has a forwardlyprojecting arc-shaped flange 11 having a hole in it, and a circular-projecting rear portion 1)", which rests on the fifth-Wheel B. Lugs 71 areprovided at each side of the laterallyextendiug wings I), and the bolster K fits in between these lugs and is secured in position by the bolts 7a, which pass through the lugs and the bolster, as indicated in Fig. 1. The bolster is preferably a steel bolster, hollow or formed with a channel malleable cast bar, the end being provided with slots or notches 7c". The uprights K at the end of the bolster are provided with the depending tongues, reverse T-shape in cross-section, which fit into the slots in the ends of the bolsters, being suitably held in position by bolts.

L is the reach,-which is provided at the front with the top and bottom bars Z Z, respectively, the upper bar Z extending upwardly at an incline and both bars extend- -ing forwardly to a point directly over and unof the reach passes through a U-shaped strip M, through the ends of which also the bolts 76 pass, thereby securely bracing the rear end 'of the reach to the axle.

It will be noticed from the construction described as to the tongue and the axle that the draft by my construction is exerted directly on the axle and not as heretofore been commonly the case at a point above the level of the axle. The other parts of the device heretofore described are also specially designed to first minimize the friction on the axle-arm and simplify the construction of the remaining gear generally.

What I claim as my invention is- 1. In a running-gear for vehicles, a divided axle comprising two semicylindrical bars suitably held together in the center, the said bars having tapering ends, means for holding the ends apart, said ends being screw-threaded, substantially as described.

2. In a running-gear for vehicles, a divided axle comprising two bars suitably connected together in the center and having end arms with ribs extending between and holding the bars apart at each end and separating-blocks provided with flanges at the top and bottom extending at each side onto the two bars as and for the purpose specified.

3. The combination with the divided axlebar, of an arm comprising a sleeve-shaped inner end with a tapered central bar attached to or forming parts of the same and extending between the divided axle-bars and provided with flanges and the threaded end formed partially on the divided bar and central bars as and for the purpose specified.

t. The combination with the-divided axle- .bar, of an arm comprising a sleeve-shaped inner end with a tapered central bar attached to or forming part of the same and extending between the divided axle-bars and pro- WILLIAM LOWERY MARSHALL.
